So this is my first time rebuilding an engine.. ( still in high school, on a high school budget). When I was cleaning up my crankshaft I noticed it had just a tiny, tiny nick in it. I cant even hardly feel it with my finger. But what do you think? Its the one going sort of left to right not the one that goes up and down. The rest are not scratches but grease from my finger. Thanks a lot guys, I am honestly debating on just selling this whole project if I keep running into more trouble.
